  • zeroize entire capacity of String
  • zeroize entire capacity of Vec

1.1.0 (2019-12-02)

  • Add TryZeroize trait
  • Add From<Z: Zeroize> impl for Zeroizing<Z>
  • Remove bytes-preview feature

1.0.0 (2019-10-13)

  • Initial 1.0 release 🎉
  • zeroize_derive: Remove legacy no_drop attribute support

  • (Optionally) Impl Zeroize for Bytes and BytesMut

0.10.0 (2019-08-19)

Barring unforeseen circumstances, this release aims to be the last 0.x release prior to a zeroize 1.0 release.

  • Disable zeroize_derive Cargo feature by default
  • Remove std feature in favor of alloc; MSRV 1.36+
  • Deprecate #[zeroize(no_drop)] attribute
  • Use 1.0 proc-macro2, quote, and syn crates

0.9.0 (2019-06-04)

NOTICE: This release changes the default behavior of derive(Zeroize) to no longer derive a Drop impl. If you wish to derive Drop, you must now explicitly add a #[zeroize(drop)] attribute on the type for which you are deriving Zeroize.

  • Remove CPU fences

  • Add ZeroizeOnDrop marker trait + custom derive
  • Custom derive support for Zeroize
  • Rename ZeroizeWithDefault to DefaultIsZeroes

0.5.2 (2018-12-25)

  • Add debug_assert! to ensure string interiors are zeroized

0.5.1 (2018-12-24)

  • Avoid re-exporting the whole prelude

0.5.0 (2018-12-24)
